When I connected up my beer engine last night I noticed that it wasn’t drawing the cleaning water up as well as it should, so I thought that it might need some maintenance. So this evening I took it apart. It turned out that all it needed was a good clean, but I thought you might like to see a few photos of what it looks like inside.
Here’s the engine removed from the counter and ready to be cleaned:
This is what it looks like round the back. It’s dead simple. The beer line connects to the nozzle at the bottom, and the silver cylinder contains the pump mechanism.
Close up of the mechanism before disassembly – note the hideous beer stains.
The whole thing can be disassembled without any tools. Ideal to allow it to be maintained easily in a busy pub. Basically it’s a milled steel cylinder, held fast by two long bolts that fix to the underside of the unit. This shows the first bolt being removed:
Then the bottom part of the pump can be removed:
And the seal ring:
Then the main steel cylinder can be removed revealing a rather dirty piston:
Hmm. And we drew our beer through that?
All clean and ready for re-assembly:
Replacing the steel cylinder:
Testing:
And back in place on the counter in the garage:
